Ifilimu yokudonsa ifilimu yepulasitiki esobala enezinhlobonhlobo zokusetshenziswa, ikakhulukazi esetshenziselwa ukupakisha, ukuvikela nokuvikela izinto.Ifilimu edwetshwe ngesandla ngokuvamile yenziwe nge-polyethylene (PE) noma i-polyvinyl chloride (PVC) nezinye izinto, futhi inemisebenzi efana nokungangeni kwamanzi, uthuli, umswakama-umswakama, nokunqanda ukubola.Ubukhulu, ububanzi, umbala, amandla nezinye izici ze-Hand Stretch Film zizothinta umphumela wayo wokusebenzisa, ngakho-ke kubaluleke kakhulu ukukhetha ifilimu yokwelula yesandla elungele ukusetshenziswa kwakho.

Ukukhetha ifilimu yokwelula isandla okulula ukuyisebenzisa, udinga ukunaka amaphuzu alandelayo:
1. Ukujiya kwe-Membrane: Ngokuvamile, ukushuba okukhulu kolwelwesi oludwetshwe ngesandla, kuba ngcono ukusebenza kokuvikela amanzi nokuvikela, kodwa intengo izokhuphuka ngokufanele.Ngakho-ke, idinga ukukhethwa ngokuvumelana nezidingo zokusetshenziswa.

2. Impahla ye-Membrane: Kunezinhlobo eziningi zezinto zokwakha ulwelwesi oludwetshwe ngesandla, njenge-PE, i-PVC, i-PP, njll. Izinto ezihlukene zinezakhiwo ezahlukene, okudingeka zikhethwe ngokuvumelana nezidingo zokusetshenziswa.

3. Ububanzi befilimu: Ububanzi befilimu edwetshwe ngesandla nakho kuyisici esidinga ukucatshangelwa.Ngokuvamile, ububanzi bukhulu, indawo ekhavayo inkulu, kodwa intengo nayo izokhuphuka ngokufanele.

4. Amandla efilimu: Amandla okugoqa kwefilimu enwetshiwe nakho kuyisici okufanele sicatshangelwe.Uma udinga ukugoqa izinto ezisindayo noma ukugcina isikhathi eside, udinga ukukhetha ukugoqa okuqinile kwefilimu.

5. Umbala wefilimu: Umbala wefilimu edwetshwe ngesandla nawo uyisici okufanele sicatshangelwe.Uma udinga ukuhlukanisa noma ukuhlukanisa izinto ezihlukene, ungakhetha ifilimu edwetshwe ngesandla enombala ohlukile.

Ukufingqa, ukukhetha ifilimu edwetshwe ngesandla esebenziseka kalula kudinga ukukhethwa kuye ngokwezidingo ezithile, kucatshangelwa izici ezifana nempahla, ukujiya, ububanzi, amandla kanye nombala.
